' CATCH DEVICE FOR ADJUSTING STRAPS FOB, LENGTH.

Specification of Letters Patent.

Patented July 12, 1921.

Application filed December 21, 1920. Serial No. 432,199.

To all whom it may concern:

Be it known that I, JAMES H. LAMONT, a citizen of the United States,resident of Coatesville, in the county of Chester and State ofPennsylvania, have made a certain new and useful Invention in CatchDevices for Adjusting Straps for Length; and I declare the following tobe a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it appertains to make and use theinvention, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

Figure 1 is a perspective view of the invention as applied.

Fig. 2 is a central longitudinal section of the invention.

The invention has relation to adjustable straps for supporting musicalinstruments such as Saxophones and useful for other purposes, theinvention residing mainly in an improved catch device for adjusting the2 strap for length more quickly and easily.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth.

In the accompanying drawings illustrating the invention, the numeral 2designates the strap, which in the present instance. passes around theneck of the musician and is provided at one free end with a snap hook 3and at its other free end portion with an adjustable loop 4: with whichis engaged another snap hook 5, the two snap hooks being engaged with aneye 6 of the instrument 1n supporting the same.

In adjusting the loop 4: for length to 4 shorten or lengthen the strapas a whole, it is common touse an ordinary buckle, and in place of thisapplicant provides a catch device, consisting of a body 7 of sheetmetal, having a plane bottom 8, and parallel upturned flanges 9, agripper lever 10, being fulcrumed intermediately of its length at 11,through downturned lugs 12, thereof to said flanges, and having one arm13 bent downwardly into position to engage the strap and its other arm14 forming the top of the catch device and extending between saidflanges toward the rear end of and projecting beyond the same, at 15, toenable the lever to be more readily operated.

A U-form spring 16, has one arm located beneath the arm 14 of thegripper lever close thereto, and the other arm engaged with a transversepin 17, connecting the flanges 9 at one end portion thereof, the strap2, passing beneath the pin 17 and beneath the gripper end of the lever10, and being thereby confined close to the bottom 8, and the springacting to normally hold the downturned or gripper end of the lever inengagement with the strap to thereby retain the adjustment of the strapfor length.

In the use of the invention, the lever is depressed by finger pressureupon the tail arm thereof, thereby releasing the strap, after which thecatch device as a whole (to which the other end portion of the strap isconnected at 18, through transverse pin 19) is slid along the strap toshorten or lengthen the loop 1, and upon release of said lever, thestrap will be engaged thereby to retain the adjustment. Or, anothermethod of use, is to hold the catch device with one hand, and pull thestrap therethrough with the other hand, the frictional engagement of thelever with the strap retaining the adjustment upon release of the parts.

The body of the device with its plane bottom and upturned lateralflanges forms an inclosure for the parts working therein, which arethereby concealed from view and protected, and prevented from catchingin the clothing.

I claim An open-ended box-form device for adjusting a strap for length,consisting of a sheet-metal body having a bottom and lateral flangesextending the full length thereof, a lever fulcrumed between saidflanges and having an inturned arm extending toward said bottom andadapted in cooperation therewith for frictional engagement with a strap,a transverse strap-confining pin connecting said flanges at one endportion of said body and spaced apart from said bottom, and a transversestrap-engaging pin connecting said flanges near the other end portion ofsaid body adjacent to said inturned arm, said lever forming one Intestimony whereof I'afiix my signature side of said device and beingprotected in presence of two Witnesses. throughout the major portion ofits length by said flanges, and a spring located between V E LAMONT 5said flanges and bearing at one end against Witnesses: j

said lever and at the other end against said R0131. H. BERNAU,
